The ongoing process of keeping a bird's beak at proper length and shape through natural wear — chewing wood, cuttlebone, foraging toys, and mineral blocks. Overgrown beaks require veterinary attention.
Overgrown or misshapen beaks indicate liver disease, nutritional deficiency, or injury — not just a cosmetic issue.
Provide a rotation of destructible wood toys in different hardnesses — soft pine for daily chewing, harder manzanita for serious beak wear.
